Disclosed are a method and apparatus for providing a linking service between a vehicle AVN system and a smartphone based on a virtualization framework. An apparatus for providing a linking service between a vehicle audio video navigation (AVN) system and a smartphone, includes a host operating system for managing an operation and a state of a host process and AVN application, and managing hardware resources included in the apparatus for the host process and AVN application, a guest operating system for managing an operation and a state of a guest process/the smartphone linkage application, and a hypervisor for emulating the hardware resources according to a control signal of the host operating system to allocate a virtualized hardware resource to the guest operating system. Therefore, the present disclosure has an advantage of continuously providing an existing AVN function irrespective of an error of a function of linking a vehicle AVN system and a smartphone.

Disclosed herein is a canal type earphone with a pressure equilibrium means, capable of eliminating a pressure difference between a user's external auditory meatus and an outside during wearing of the canal type earphone. A pressure equilibrium means includes a side air passage through which air within a tube or air within a speaker unit in the canal type earphone is discharged to a side surface of a gasket or a side surface of the speaker unit, and a rear air passage through which air in the side surface of the speaker unit is discharged to the rear of the speaker unit.

Canal type earphone with pressure equilibrium means

Disclosed is a microspeaker with an inner resonance chamber, more particularly a microspeaker with an inner resonance chamber which improves quality of sound and enables slim and compact design of the microspeaker by blocking rearward sound generated at the rear side of the vibration plate to prevent interference of a rearward sound with a forward sound generated at the front side of a vibration plate and installing a chamber with a specific volume within the microspeaker to allow the rearward sound to cause resonance.

Microspeaker with inner resonance chamber

Disclosed herein are a graphene hybrid material and a method for preparing the graphene hybrid material, the graphene hybrid material comprising: a matrix having lattice planes disconnected on a surface thereof; and layers of graphene which are epitaxially grown along the lattice planes disconnected on the surface of the matrix such that the layers of graphene are oriented perpendicularly to the matrix, and which are spaced apart from each other and layered on the matrix in the same shape. The graphene hybrid material can be usefully used in the fields of next-generation semiconductor devices, biosensors, electrochemical electrodes and the like.
